Artocarpin, a prenylated flavonoid isolated from Artocarpus altilis heartwood, has emerged as a promising multi-targeted bioactive compound for combating UV-induced skin aging. This review provides a comprehensive overview of the molecular mechanisms and photoprotective efficacy of artocarpin across in vitro, in vivo and clinical study, based on the peer-reviewed literature published between 2012 and 2025, retrieved from PubMed, Scopus, and Web of Science. Delivery strategies designed to overcome the inherent physicochemical limitations of artocarpin on skin penetration are also discussed. Artocarpin demonstrates antioxidant effects through both direct free radical scavenging and activation of the Nrf2-ARE pathway, providing sustained cellular defense. Its anti-inflammatory properties target multiple signaling cascades, including the NF-κB and MAPK pathways, effectively mitigating UV-induced inflammatory response. The compound maintains dermal matrix homeostasis by inhibiting matrix metalloproteinase-1 (MMP-1) expression while preserving collagen synthesis and fibroblast mechanical function. Additionally, artocarpin exhibits selective apoptosis modulation, being cytoprotective in normal keratinocytes while acting as pro-apoptotic in damaged or abnormal cells, thereby supporting tissue homeostasis. It also inhibits melanogenesis through anti-inflammatory mechanisms rather than direct tyrosinase inhibition. Furthermore, artocarpin has been shown to induce autophagic cell death in certain cell lines; however, its role in UV-induced skin damages remains to be clarified. Despite these promising biological activities, the poor water solubility (<0.1 mg/mL) and high lipophilicity (log P ≈ 5) of artocarpin significantly limit its skin penetration. Lipid-based delivery systems, including liposomes, transfersomes, ethosomes, and nanostructured lipid carriers (NLCs), are presented as effective strategies to enhance transepidermal delivery, with each system offering distinct mechanistic advantages. Further investigations should prioritize the safety of artocarpin within each delivery system, as well as the synergistic co-encapsulation with complementary natural antioxidants to simultaneously target multiple mechanisms involved in UV-induced skin damage, thereby broadening its application in the cosmeceutical industry.

Cancer is a progressive disease of multi-factorial origin that has risen worldwide, probably due to changes in lifestyle, food intake, and environmental changes as some of the reasons. Skin cancer can be classified into melanomas from melanocytes and nonmelanoma skin cancer (NMSC) from the epidermally-derived cell. Together it constitutes about 95% of skin cancer. Basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (CSCC) are creditworthy of 99% of NMSC due to the limited accessibility of conventional formulations in skin cancer cells of having multiple obstacles in treatment reply to this therapeutic regime. Despite this, it often encounters erratic bioavailability and absorption to the target. Nanoparticles developed through nanotechnology platforms could be the better topical skin cancer therapy option. To improve the topical delivery, the nano-sized delivery system is appropriate as it fuses with the cutaneous layer and fluidized membrane; thus, the deeper penetration of therapeutics could be possible to reach the target spot. This review briefly outlooks the various nanoparticle preparations, i.e., liposomes, niosomes, ethosomes, transferosomes, transethosomes, nanoemulsions, and nanoparticles technologies tested into skin cancer and impede their progress tend to concentrate in the skin layers. Nanocarriers have proved that they can considerably boost medication bioavailability, lowering the frequency of dosage and reducing the toxicity associated with high doses of the medication.

This research aimed to develop and evaluate a novel multi-ethosome (ME) system for the dermal delivery of terbinafine hydrochloride (TH) as a new approach to fungal infection treatment. TH-loaded MEs were successfully prepared using cinnamaldehyde as a penetration enhancer. Mean diameter of ME was found as ~100 nm with monodispersed size distribution. Drug entrapment efficiency reached up to 86% ± 1.4%. MEs exhibited excellent colloid stability and no drug leakage after 2 months of storage. In contrast to a commercial Lamisil^® cream, ME significantly improved the targeting efficiency by increasing the fluidity of stratum corneum layer, revealed by attenuated total reflection Fourier transformed infrared spectroscopy (ATR-FTIR). The dermal targeting effect was visualized using confocal microscopy. Moreover, skin irritation and allergy tests showed that ME was not irritating to the skin. The improved antifungal activity of ME was proved in vitro on Candida albicans strains by minimal inhibitory concentration (MIC) assay. This study paves the way towards design of MEs for dermal fungal infection treatment. Full article

Sulforaphane is a multi-action drug and its anticancer activity is the reason for the continuous growth of attention being paid to this drug. Sulforaphane shows an in vitro antiproliferative activity against melanoma and other skin cancer diseases. Unfortunately, this natural compound cannot be applied in free form on the skin due to its poor percutaneous permeation determined by its physico-chemical characteristics. The aim of this investigation was to evaluate ethosomes^® and transfersomes^® as ultradeformable vesicular carriers for the percutaneous delivery of sulforaphane to be used for the treatment of skin cancer diseases. The physico-chemical features of the ultradeformable vesicles were evaluated. Namely, ethosomes^® and transfersomes^® had mean sizes <400 nm and a polydispersity index close to 0. The stability studies demonstrated that the most suitable ultradeformable vesicles to be used as topical carriers of sulforaphane were ethosomes^® made up of ethanol 40% (w/v) and phospholipon 90G 2% (w/v). In particular, in vitro studies of percutaneous permeation through human stratum corneum and epidermis membranes showed an increase of the percutaneous permeation of sulforaphane. The antiproliferative activity of sulforaphane-loaded ethosomes^® was tested on SK-MEL 28 and improved anticancer activity was observed in comparison with the free drug. Full article
